Manifold Flow Indicator columns
The wilger visual ball flow manifold columns are infinitely stackable, so they can be built into any required configuration.
Manifold flow indicators come in three different columns sizes, broken down by recommended flow ranges:
Ultra low flow column: 0.01 – 0.24 us gpm flow rates
low flow column: 0.05 – 0.65 us gpm flow rates
standard flow column: 0.07 – 2.70 us gpm flow rates
Isolated feed flow indicator columns
The isolated feed columns are used to monitor multiple single feed lines. For example, monitoring individual lines coming out of a squeeze pump.
Isolated feed flow indicators come in two different columns sizes, broken down by recommended flow ranges:
Low flow column: 0.05 – 0.65 us gpm flow rates
standard flow column: 0.07 – 2.70 us gpm flow rates
| Max Operating Pressure | 100 PSI (7BAR) |
| Max Operating Flow Rate | Up to 8.0 us gpm (for standard flow column) |
